The errors that you have attached below are not necessarily related to
the reason your simulation is failing. The QC reporting mechanism
relies on results generated during the course of a successful
simulation, and the fact that you are unable to a simulation is the
reason
for some of the nonsensical numbers in the QC reporting results. Check
the .sim file for information on why the simulation won't run.<br>
